To aZZ whmn it may concern:

Be it known that I, JoiuXN Gicono FAYIR, a subject of the Emperor of Germany, residing at Gottmadingen, Baden, Germany, have invented Improvements in Spi2mi11g- Machincs,of which the followiugis a specification.

This invention relates to spinningachines; and the object of this lilftiltlOll is to construct such machines more especially adapted for spinning hemp in such a mannrr as to render them capable of bei' g driven at high speedssay at live thousand revolutions per minute and over. The spinningmachines ordinarily used hitherto are not: adapted to be driven at a speed exceeding one thousand to fifteen lmndred revolutions per minute by reason of the clleet f cent rifugal action, because 1 re fliers or chines comprise rigid transverse pier which bend and finally break at high speeds of revolution. It has been atteuuned to make the fliers of spinning-machines of elastic materialsuch as, for instance, of a pianoforte-w1rewh1eli in revod bundle of yield to centrifugal action and bender belly outward; but this arran ement also the drawback that the spnm e'-hier must L; be efficiently protected by means of a latticeguard in order to prevent danger arising therefrom.

Now in machines according to the present invention spinningfliers are entirely dispensed with, and the thread is carried round only by means of arms which are arranged at both ends of the bobbin and which :1 caused to revolve at equal speeds of revolution in any desired manner.

In the drawings, Figure 1 is a ver. cut of a spinning-machine constructed according to the present invention. Fig. 2 is a vertical cross-section through the wheel-gear modified in such a manner that by means of the same driving-wheels two spindies are driven. Fig. 3 shows a method of driving the machine by means of synchronous electromotors and a change in the arrangemem for guiding the thread. Fig. is a lateral view of the mechanism for driving the shutole-guide.

Hollow spindles 3 and 6, on which are rigidly mounted the spinning-arms i and 5, are placed in the two frames 10 and 11, so that they can turn, and are uniformly driven by means of the two couples of too-.hcd wheels 12 13 and 14 15 in such a manner that Wheels 12 and 14 are placed on one common would i 5 guide 8.

i it with a reciprocating motion.

shaft 16, to which a rotary motion is imparted through pulley 17. From the spindles 3 and 6 arev suspended in the form of siirrups two hanging supports 18 and 19, which form the supports for spindle 20, provided with cross-thread and carrying the Said supports 18 and 19 have ballbearings 16 and 19 on the spindles 3 and 6.

The thread 1 is fed into the hollow spindle 3 by two rolls 2. After leaving the spindle 3 the thread is guided over the arms 4 and 5, through the hollow spindle 6, and through a passage 7 in the support 19 to the guide 8, whence it is wound up on bobbin 9.

The bobbin is secured and driven in the following manner: 0n the right end of spindle 3 firmly secured disk 21. Into the latter is pressed \Yllll an interposed asbestos plate 22 a second disk 23,1nto the slightly-conical depression of which the front disk of bobbin 9 is pressed. Disk 23 has two pivots, one of which projects into an aperture in the spindle 3 and the other into an aperture in bobbin 6. (hi the right side the bobbin is pressed in'.o the disk 21, the necessary pressure being proouced by means of spring 25, which abrus on the one side against 24 and on the other side against plate 26. The pressure proi'luced by the spring is effective enough to cause the bobbin to be taken along by means of friction with the rotary lllOtlOil of disk 21. 2 1 and 26 turn loosely around the axis 27, which is secured in suppoiuing part 7, connected with the hanging support 19. in order to reduce the friction be=ween plate 26 and supporting part 27 a bail-be 28 has been provided between them, re the tension of spring 25 can be adjused by nut 29, secured by part 30. The spindle 20, carrying guide 8, is driven I from spindle 6 by the double worm-and-wheel arrangement 31 32 33 3 1. (See Fig. 1 and ig. el.) Spindle 20, being provided with left and right. handed threads, which cross each other, the shuttle is made to travel 011 The first twist is given to the thread directly behind the rolls 2. A further short twist is brought about in that; place where it enters over spinning-arm 5 into the hollow spindle 6.

I As the thread rotates at a high rate of speed,

it: would be caused to bulge out by the centrifugal force if hanging free in its entire length. it is therefore guided by slide-rings 35, which are secured to the machine-frame.

The above-described machine can also be sea used to advantage as twisting or rope machine. It may further be constructed With two pairs of spindles which are both driven by the same shaft 16. fication in a vertical cross-section through the Wheel-gear With the numerals of reference like those used in Fig. 1. lnsLead of being driven by Wheel-couples 12 13 and 14 15 spindles 3 and 6 can also be operated by means of synchronous electromoeors which are placed directly on the spindles. This construction is represented in Fig. 3, in which, besides the known numerals of reference, 36 is the armature, and 37 the bobbins, of the motor.

WVhat I claim is- 1. In spinningmachines, the combination with a bobbin, of tWo independent arms re- Fig. 2 shows this modil l l volving at equal speeds, said arms being located on each side of the bobbin, means for 20 cated on each side of the bobbin, means for 2 5 revolving said arms equal speeds, and a plurality of rings encircling the bobbin and lying bet veen the arms, substantially as de scribed.
